Abstract
Vorrichtung zur Einstellung des Anstellwinkels von Blättern (12) eines Rotors (10), bei der der Antrieb dieser Vorrichtung über einen stehenden Hydraulikzylinder (24) erfolgt, der konzentrisch zu der Rotationsachse des Rotors (10) angeordnet ist, und dessen Kolben (22) mit einer Stange (20) verbunden ist, auf der drehbar, aber in Axialrichtung fest ein Lenkungsring (18) angeordnet ist, der Lenkungsstifte (16) auf seiner Außenseite trägt, die an den Innenkanten der Rotorblätter (12) angreifen und deren eine Ecke in Axialrichtung verschiebbar antreiben, während die andere Ecke der Innenkanten der Rotorblätter (12) um eine Achse senkrecht zur Rotationsachse des Rotors (10) drehbar aber ansonsten fest am Rotor (10) gelagert ist, und die andere Ecke der Innenkanten der Rotorblätter (12) mittels eines Stiftes (28) in der Nabe (14) gelagert ist, wobei der Stift (28) nach innen hin in einen Kugelkopf (32) ausläuft, der in einer Nut (34) im Lenkungsring (18) aufgenommen ist.Device for adjusting the angle of attack of blades (12) of a rotor (10), in which the drive of this device takes place via a vertical hydraulic cylinder (24), which is arranged concentrically to the axis of rotation of the rotor (10), and whose piston (22) is connected to a rod (20) on the rotatable, but in the axial direction fixed a steering ring (18) is arranged, the steering pins (16) carries on its outer side, which engage the inner edges of the rotor blades (12) and whose one corner in Drive axially displaceable, while the other corner of the inner edges of the rotor blades (12) about an axis perpendicular to the rotational axis of the rotor (10) rotatable but otherwise fixed to the rotor (10) is mounted, and the other corner of the inner edges of the rotor blades (12) by means a pin (28) is mounted in the hub (14), wherein the pin (28) terminates inwardly in a ball head (32) which is received in a groove (34) in the steering ring (18).
Description
Die Erfindung betrifft eine Vorrichtung zur Einstellung des Anstellwinkels von Blättern eines Rotors. Bei vielen Rotoren ist es wünschenswert, die Steigung der Rotorblätter verstellen zu können, um die Geschwindigkeit des Luftstromes unabhängig von der Drehgeschwindigkeit des Rotors regeln zu können und insbesondere um die Antriebsrichtungen vorwärts und rückwärts umstellen zu können, ohne die Drehrichtung des Antriebes umkehren zu müssen. Solche Einstellvorrichtungen für Rotoren gemäß dem Stand der Technik erfordern Zahnräder und/oder Zusatzmotoren, deren Gewicht insbesondere in der Luftfahrt und in der Anwendung bei Luftkissenfahrzeugen äußerst problematisch ist.The The invention relates to a device for adjusting the angle of attack of leaves a rotor. In many rotors, it is desirable to increase the slope of rotor blades to be able to adjust about the speed of the air flow regardless of the speed of rotation to be able to control the rotor and in particular to the drive directions forward and backward to be able to change without the To reverse the direction of rotation of the drive. Such adjusting devices for rotors according to the state The technology requires gears and / or Auxiliary motors whose weight is particularly important in aviation and in the application of hovercraft is extremely problematic.

Es ist daher Aufgabe der Erfindung, eine solche Vorrichtung zur Einstellung des Anstellwinkels von Blättern eines Rotors dergestalt weiterzubilden, dass sie erheblich einfacher und vom Gewicht her leichter ausgeführt werden kann.It is therefore an object of the invention, such a device for adjustment the angle of attack of leaves a rotor in such a way that it is much easier and lighter in weight.
Erfindungsgemäß wird diese Aufgabe mit den Merkmalen des Anspruchs 1 gelöst.According to the invention this Task solved with the features of claim 1.
Die Erfindung wird im Folgenden anhand des in der Zeichnung darstellten Ausführungsbeispieles näher erläutert. Es zeigt:The Invention will be described below with reference to the drawing Embodiment explained in more detail. It shows:

Die Erfindung erfordert für die Verstellung des Anstellwinkels der Rotorblätter keine Zahnräder und keine Zusatzmotoren. Die Erfindung ist daher für leichtere und schwächer motorisierte Luft- und Luftkissenfahrzeuge sehr vorteilhaft. Grundsätzlich ist die Erfindung jedoch für alle Fahrzeuge verwendbar, die mittels Rotoren angetrieben werden, die in fluiden Medien arbeiten, also beispielsweise auch für Flugzeuge und Schiffe.The Invention requires for the adjustment of the angle of attack of the rotor blades no gears and no additional motors. The invention is therefore for lighter and weaker motorized Air and hovercraft very beneficial. Basically, that is Invention, however, for all vehicles that are powered by rotors, who work in fluid media, so for example also for airplanes and ships.
